COOKER.

Application'filed March s i, 1927. Serial iIoL- 179,899.:

, This invention relates particularly to that type of cookers used in the cooking and sterilizing of canned goods.

It is one object of the i vide a cooker whereby the cans may be cooled under pressure; subsequent .to the cooking process, thereby preventing burst-' ing of the cans.

It is another object of the invention to provide a cooker or the character indicated whereby the cans may behandledand operated upon individually thereby eliminating most of the friction ordinarily developed in those cookers where the cans' are fed through a single chamber. I i a It is also an object of the invention to 1 i provide a device of the character indicated having a Splurality of, conical chambersformedjtherein at right angles-tothe plane thereof and adjacent its, outer perimeter with which each chamber communicatesby means of a slot, 2. Thelarger end of the chamber communicates with the exterior'qof v the element by means of an opening 3.

At 4 I show a plug fitting snugly in chamher 5 and adapted to rotatev therein, and

provided with a chamber 6 having a single 15 justed by means of screws 10 passing through the collar and engaging theelementopening therein as at 7 adaptedto register with the opening. 2. A spring '8 is inserted between the smaller endfof plug 4 and the adjacent end of chamber 5, andtheplug is held in place in chamber 5 by means of a collar .9ifitting over its outer end andad- 11. A pin 11 projects from theouter end of plug 4'througl1 collar 9 and is fitted with'a spur ;gear 12. :By means of this construction the plugmay be rotated in the-chamber 5 to bring openings 7 and 2 intoalignment atdesired intervals, and asnug fit maybe maintained between the plug4and the wall of chamber 5 by #manipulating'screws 10.

At 13, 14,15,16 are shown conduits en nvention to procircling the inner periphery of the element 1. The conduits 13 and 14 communicate with each chamber 5 at a given point a317,- and the conduits ,15, 16 communicate with each chamber at a given spaced distance from the said conduits'13 and ,14 as shown p at 18-. I The arrangement of the openings 2 and 7 and conduits 17 and 18 is such that when the plug- 4 is rotated in the direction indicated by the arrow 19 the opening 7 will move out of communication with opening 2 and j intocommunication with conduits 17,

then out of communication with conduits 17 and into communication witl1 conduits 18, and then out of communication withconduits 18 and into registration with opening 2.

A suitable supporting frame for thestructure is shown at 19 with bearings at 29 supporting fixed conduits 30 and 31 aligning with the .axis of rotation of the element 1.

- A hollow hub connected to element 1 by spokes 32 is shown at 33 andvdivided. into 2 two chambers 34 and 35 by a partition 36. The ends of thisv hub are journaled in the fixed conduits 30 and 317% shown. Con- I necting conduit 13 with chamber 34 is a conduit 37, and connecting "conduit 15 ,with chamber 35 is a conduit 38.

Axially mounted in eac and I 3 5(andto revolve therewith is asmaller r chamber as 39 and 40, and each of these smallerchambers isfljournalled in fixed con duitsas and 42. g The conduit 30 communicates with a source of steam under' pressure,finot shown, and the conduit 41 is an exhaust for the-same. municates with a source i of cooling .airv under The conduit 31 com ressure, and the conduit 42 is an exhaust tor the same. When the chamber 6 registers with conduits 13' and 14 at 17 then-steam. under pressure flows through 30, 34, 37, 13,

17 into closed chamber 6, thence thr0ugh'14,

43, 39, 41. A restricted passage is provided for the exhaust because its principal {tunetion is to permit a quick movement of the steam into all of the chambers. I

a When the chamber 6 is moved intojregis- L tration with the conduits 15 and 16- at 18, then cooling air or other fluid isintroduced under pressure, flowing through 31,335, 38,

15, 18 into chamber 44, 40. and 42;

The annular element may be rotatedin; I

any 1 suitable manner as; by a rack and pinion 45,;and theseveralgears are operatedrat desired intervals by me'ansfo 'f segmental 6, thence through 16 ears 46, 47 and 48 mounted on support 1 9. he gear 47 is adjustably mountedin support 19 as indicated at 49 for the purpose hereinafter set forth Anysuitable means is provided for introducing cans into the machine as indicated at 50, and a suitable,

receiving means is positioned at 51.

Assuming now that the device is in full operation with a supply of cans being fed into the machine at 750, where openings 2- and- 7' are in register. The rotation of element 1" moves each spur gear 12 into engagement with gear 46 thereby rotating the part-4: a distance to bring openi-n 7 into registration with conduits L7, and a mitting; steam under pressure into the chamber 6,

as above described. The cooking'process continues until the gear 12 engages gear 47 whereupon the part 4 is rotated-a distance to bring the opening 7 into registration with conduits 18, whereupon the steam is driven out and replaced'with a cooling fluid as hereinbefore described: The cooling process Y therethrough continues until the'gea'r 12 engages 'gear 48, whereupon thepa-rt- 4 is; again rotated a distance until openings? and 2- are again in register and the can permitted to discharge It may now it maybe subjected to the cooking operation for any desired length of time by suitable adjustment ofthe' gear 47 or variation in the speed of rotation of the element 1, or both. This process may be followed by any desired period of cooling under pressure, thereby eliminating the bursting of, cans, a

' matter of frequent occurrence "when cans are discharged directly from' a cooker into the atmosphere, and greatly reducing the time over those methods where'the cansare removed from a cooker and passed through a c'oolingchamber.

It may be further pointed out that bymeans of this construction desired results I may be obtainedwith much less steam or cooking fluid thanrequired in the cookers formerly used, and the steam may be used at much higher pressures, thereby materiallyshortening the time of cooking. i I a It is to be understood, of course, that while I have herein shown and-"described but one specific embodiment ofthe invention, changes in form, construction and method of assem- 7 periods," said chamber and housing having registrable openingsgformed ;therein adapted to permit the passage of cans therethrough',

said passage and ports.

r be readily seen that when a can has been introduced into a chamber 6' means for successively introducing a cooking fluid and then acoohng fluid into said chamber between the said periods oi rela-tiverotation.
